1.1.6 TimeZonesOfLocale ( loc )

1.1.7 CharacterDirectionOfLocale ( loc )

The abstract operation CharacterDirectionOfLocale takes argument loc (an Intl.Locale) and returns "ltr" or "rtl". The following algorithm refers to Locale data specified in UTS 35's Layouts Elements. It performs the following steps when called:

-
  1. Let locale be loc.[[Locale]].
  2. If the default general ordering of characters (characterOrder) within a line in locale is right-to-left, return "rtl".
  3. Return "ltr".
 +
  1. Let locale be loc.[[Locale]].
  2. Let script be GetLocaleScript(locale).
  3. If script is undefined, then
    1. Let maximal be the result of the Add Likely Subtags algorithm applied to locale. If an error is signaled, return "ltr".
    2. Set script to GetLocaleScript(maximal).
    3. If script is undefined, return "ltr".
  4. If the default general ordering of characters within a line in script is right-to-left, return "rtl".
  5. Return "ltr".
 Note
- When the direction of default general ordering of characters (characterOrder) within a line in the locale cannot be determined, or is not right-to-left, "ltr" will be retruned. + When the direction of default general ordering of characters within a line in the script cannot be determined, or is not right-to-left, "ltr" will be retruned.
